Application progress of satellite archival tags technique in large nekton

Abstract:

Mastering the migration and distribution of large nekton is the basis for analyzing their population dynamics, and carrying out population conservation and management. However, large nekton has strong swimming ability, wide range of activities and difficulty in recapture, so the traditional tagging technology has great limitations. Satellite Archival Tags technique has become one of the effective technical means to study the population changes and behavioral habits of deep-sea large nekton because of its features of not relying on retrieval, large data collection volume and high accuracy. Currently, mainstream Satellite Archival Tags are developed based on the Argos satellite system and transmitted via satellite channels, which has significant advantages over traditional tags that rely on sign recovery. This paper reviews the working principle, development history and main types of Satellite Archival Tags, introduces the main application progress, summarizes the problems and presents the research outlook, aiming to provide reference for the study of population dynamics and behavioral habits of large nekton.
